In this research, we have demonstrated the uptake of Sr²⁺ during the formation of biomass-MnO_X. Biomass-MnOx ware produced by reduction of KMnO₄ with Pseudomonas fluorescens in 40 mL of 0.1 M NaCl containing Sr²⁺. Our results indicate that Sr²⁺ was sorbed by the biomass-Mn oxides in the initial stage of the coprecipitation
